Table of Contents – Find a Number Such That When 15 is Subtracted | Solution | Problem Solved
- Find a number?
- When 15 is subtracted
- From 7 times the number
- The result is 10 more than twice the number.
Important Points to Solve the Problem
Suppose number is “y”.
7y – 15 (when 15 is subtracted from 7 times the number).
2y + 10 (result is 10 more than twice the number).
So, 7y – 15 = 2y + 10
Through this equation we can easily figure out the value of “y” (y = 5 answer).
Number = ?
Required number = y
According to the given condition;
7y – 15 = 2y + 10
7y – 2y = 25
5y = 25
y = 5 answer
